PHOTOGRAPHIC PRINTING Filed Oct. 1, 1935 FIG. 3

Patented Sept. 22, 1936 UNITED STATES PATENT OFFICE 3 Claims.

My invention relates to photographic printing, and more particularly to the product, method of producing the same, and the device used therefor. The object I have accomplished is the printing from a single photographic negative, or from more than one photographic negative in alternate or regular arrangement, a series of pictures arranged artistically in a uniform curve or circle. Other objects will be hereinafter disclosed.

In the drawing accompanying this specification, and hereby made a part hereof, Fig. 1 shows a base adapted to hold the sensitized paper on which the picture is to be made. Fig. 2 is a side view of Fig. 1. Fig. 3 shows an opaque mat having an opening adapted to hold the photographic negative to be used in connection with the printing of the picture.

Fig. 4 is a fractional copy of Fig. 3 except that it shows a photographic positive instead of a negative film thereon.

Referring to Fig. 1, I have provided a base I! which has a needle pivot l8 extending upward at the approximate center. A circle having the needle pivot as the center may be marked as a guide for the purpose of dividing said circle into a plurality of sectors which on the drawing are numbered l to I6 inclusive. These marked sectors are arbitrary and the number of them can 30 be increased or diminished as desired, as such numbered sectors are intended merely as guides to be used selectively by the operator. Within the circle are devices ill, or corner pockets, which are adapted to hold the corners of the sensitized paper in a fixed position on the base.

An opaque mat 25 has an opening, or hole 26 adapted to receive the needle pivot l8 so said mat can be rotated on the pivot. This mat should be of sufiicient size to cover the whole of the sensitized printing paper. An opening 28 is cut in the mat on a radial line extending from the pivot, the size and shape of the opening being dependent somewhat on the character of the photographic negative it is desired to print. An indicator 29 is placed on a radial line. This indicator is to be used in connection with the sector marks I to IE, selectively in positioning the negative on the sensitized paper. The negative 30 is positioned to cover opening 28.

As shown in Fig. 4, a positive film 30A can be substituted for the negative film 30 for printing. In using this device the sensitized paper 2| is placed in the position shown in Fig. 1 with the needle pivot 18 extending through the approximate center of the paper, and by means of corner pockets IS the sensitized paper is held in a fixed position. The mat 25 with the assembled photographic negative is then placed over the sensitized paper with needle 18 passing through hole 26. The mat is then positioned by revolving it on the pivot so the indicating arrow 29 will point to a selected number on the dial, and an exposure 5 to the light is made. It is noted that the mat covers all of the sensitized sheet except in the sector selected for the pictures, and will nullify the exposure on the sensitized paper on all parts except the portion under the photographic negative. The mat with the negative thereon, or any other negative which may be substituted, is moved on the pivot until the indicating arrow points to another selected sector and an exposure to the light is again had. It is noted that such expo sures when made on the sensitized sheet can either overlap, merely touch each other, or be spaced apart, depending on the artistic design desired by the operator. This method of arranging the position of the picture to be made by an exposure is continued until as many pictures on the radii are made as are desired, when the exposed sensitized paper is taken from the base, developed and fixed. It is noted that the pictures printed in this manner can be arranged in a curve, and form an artistic group, can be spaced apart, or uniformly overlapped as desired.

Having described my invention I claim:

1. In a device for arranging a plurality of photographic prints on a single sheet of sensitized 0 photographic paper in a selective curved line, the combination of a base adapted to hold the photographic sheet in a fixed position, an opaque mat adapted to cover the whole of said photographic sheet except a cut out portion adapted to receive and hold a photographic film to be used in printing, means adapted to permit the mat to be moved so said open portion thereon describes the selective curve, said mat being of such shape and size that it will cover the whole of the sensitized sheet in either position thus selected.

2. A device for printing a series of photographic pictures frbm a photographic negative, consisting of a base, means for holding a sheet of sensitized photographic paper on said base, a mat pivotally attached to the base, said mat being of such size that in all positions to which it may be turned on said pivot it will cover the sensitized paper, said mat having an opening, means for attaching the photographic negative over the opening in said mat.

3. A device of the character described in claim 2 having sectors of said circle marked on the base, and an indicator on the revolving mat adapted as a guide in positioning the negatives with regard to said sectors.
